LE ROY W. WILLIS, MONTVILLE, NEW JERSEY, ASSIGNOR', BY MESNE AND DIRECT ASSIGNMENTS, I'O RAILROAD ACCESSORIES CORPORATION, OF NEW YORK, N. Y.,

A CORPORATION NEW YORK.

of Montville, in the county of Morris and.

State of New Jersey, have invented certain new and useful Improvements in Batteries, of which the following is a specification.

This invention relates to improvements in to primary batteries.

The invention has for its objects to provide a battery having an increased current capacity; to provide a battery so constructed that the parts may be readily assembled and renewed; to provide improved constructions of negative and positive elements and means for supporting the same in proper relation within the battery jar; and to provide simple means for supporting a long vtubular zinc electrode on the lower end of a negable even when the, battery jar is tilted o subjected to severe shocks.

In the accompanying drawmgs:

tive electrode are suspended from post/1 so as to permit the same to be lifted with the jar cover as a unit.

The cathode comprises an inner imperforate metal cylinder 9 and an outer perforated or reticulated metal cylinder 10, thecylinder 9, being closed at its upper end by a cap 11', having a peripheral flange 12 welded or otherwise rigidly secured to the upper end of the cylinder, and the open lowerend of said cylinder 9 is provided with an outwardly projecting circumferential flange 13. Cap 11 has astiffening or reinforcing disk 14: rivetted thereto on its under side which rests on the head of screw 4 and a clamping nut 15 is threaded, on screw 4 against the upper side of cap 11; The outer cylindrical member 10 of the cathode has an inwardly extending ring 16 rigidly secured thereto around itslower end, the bodyiportion of the ring 16 being raised above the lower edge of cylinder 10 and the outer edge thereof being bent downwardly, I

outwardly and upwardly around the lower edge of the cylinder so as to form a circular depending flange 17 The inner edge of ring 16; is bent upwardly at 16 and engages against the cylinder 9. I

Ring 16 forms the annular container which is filled with a suitable depolarizing compound 18, such as powdered copper oxide, the upperend ofthis container being closed by a removable caprlng and spacer19having a channelbody portion depending between-the upper ends ing alsovprovided with a flange 20 resting on cap 11 and an outwardly and downwardly extending flange 21, fitting around the upper in its upperside in which the depending flange 17 on the cathode engages and is also provided with a flat face 25' and an upwardly and inwardly extending beveled face 26 upon which the bottom ring 16 rests.

Each block isfformed with an upwardly extendingportion 27 provided with an ,outwardly extending lug or projection 28 overbottomof a sectional hanging an abutment or ledge 29 formed at the outer end of the block. I

The anode or positive electrode comprises a cylinder 30 formed of zinc and split from end to end as shown at 31 to permit the same to be passed downwardly about the cathode and sprung over the portions 27 of blocks 22, said zinc cylinder being provided with apertures 32 in which lugs 28 on the blocks engage. The lower edge of the anode or split zinc cylinder rests on the ledges or abutments 29 on blocks 22. A rivet 33 held to the anode forms the negative terminal of the battery and the line wire 34: of the electric circuit is connected to said rivet.

The upstanding portions 27 of the blocks hold the anode 3O spaced apart from the outer cylindrical member 10 ot the cathode or negative element. By providing the blocks with lugs 28 engaging in apertures in the anode and with abutinents 29 on which the lower end of the anode rests, the anode is positively held against endwise and tilting movements relatively to the blocks. Blocks 22 are interlocked with the sections or the negative element and are supported on said element in such a way negative element.

The depolarizing compound 18 may be renewed by removingjclosure ring 19 and pulling cylinder 10 upwardly, whereupon ring 16 will scrape the old body of mate rial oft cylinder 9. Cylinder 10 is then replaced and the space between cylinders 9 and 10 repacked withcopperoxide and ring 19 replaced. The anode may be readily replaced by springing an old anode ofi' the blocks and forcing'a new anode downwardly about the cathode. The cover may be readily removed from post t by unscrewing nuts 5 and S. The .l is filled with a suitable alkaline electrolyte preferably, ap proximately, to the level indicated by the broken line 85, Fig. 1.
